Fungus in the environment

After deciding on the new direction for the fungal infection for the animals we decided to have the fungus manifest itself in the environment as well, adding continuity and also explaining a bit more how the infection is actually spread; in all of the infection 'zones' there will be fungus spread around the environment getting gradually more severe as the player reaches the centre, or the the Spirit boss fight, the player then kills the Spirit resulting the the death of the fungus around that area of the island. The fungus would also fire spores into the environment adding a dark foggy effect to the environment and heavily enforcing the idea of the danger of the infection on the island.

The sketch is mainly serving as a reference for a 3D model based on the subject.
